Immune System Booster

My mother in law has no spleen. She has come down with a virus that her body has to fight off. I need information on something that may help her do that.

Echinacea is well studied and well known for stimulating immunity to exert its anti-viral effect. It should be taken every two hours, between meals for best effect. Garlic is anti-viral and antibiotic, especially effective if a fresh clove is taken with meals. Three cloves a day will exert a powerful effect. Licorice exerts an anti-viral effect and helps the body to regain health by supporting the adrenal glands. It can be purchased in the form of a powder or a tincture.
The diet should be high in fresh fruits and vegetables. Sugar products should be avoided because sugar decreases immunity. Foods high in essential fatty acids, such as beans, lentils, sunflower seeds and nuts will promote the health of the body cells.
